Hypertension-mediated organ damage and established cardiovascular disease in patients with hypertension: the China Hypertension Survey, 2012-2015. J Hum Hypertens 2022; 36:1092-1098. [PMID: 34799686 PMCID: PMC9734033 DOI: 10.1038/s41371-021-00635-z] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2021] [Revised: 10/29/2021] [Accepted: 11/04/2021] [Indexed: 01/25/2023]
Abstract
Hypertension is a major health burden worldwide. However, there is limited data on the status of hypertension-mediated organ damage (HMOD) and established cardiovascular (CV) disease in Chinese hypertensive patients. The aim of this study is to determine the prevalence of HMOD and established CV disease in a nationally representative population in China. A stratified multistage random sampling method was used in the China Hypertension Survey and 21,243 participants aged 35 or older were eligible for analysis in this study. For each participant, the demographic information and a self-reported medical history were acquired. Blood pressure was measured with the electronic device 3 times on the right arm, supported at heart level, after the participant was sitting at rest for 5 min. Samples of blood and urine were tested. 2-D and Doppler echocardiography were used to assess the heart's function and structures. Sampling weights were calculated based on the 2010 China population census data. Overall, the weighted prevalence of asymptomatic HMOD was 22.1%, 28.9%, 23.1%, 6.4%, and 6.2% for wide pulse pressure, left ventricular hypertrophy, microalbuminuria, chronic kidney disease, and abnormal ankle-brachial index, respectively. For the established CV disease, the weighted prevalence was 1.8%, 1.3%, 2.0%, and 1.1% for stroke, coronary artery disease, heart failure, and atrial fibrillation, respectively. The prevalence of asymptomatic HMOD and established CV disease was greater with higher blood pressure level (P < 0.05), rather than ankle-brachial index. Compared to those with uncontrolled hypertension, the prevalence of asymptomatic HMOD was lower in patients with controlled hypertension. In summary, the prevalence of HMOD in Chinese people aged 35 or older was very common, indicating a substantial future burden of both morbidity and mortality from hypertension in China. Clinical trial registration number: ChiCTR-ECS-14004641.

Abstract
Background Timely diagnosis and treatment of stage 3 chronic kidney disease (CKD) can prevent further loss of kidney function and progression to kidney failure. However, contemporary data on the global prevalence of undiagnosed stage 3 CKD are scarce. REVEAL-CKD is a multinational, multifocal and observational study aiming to provide insights into undiagnosed stage 3 CKD in a large population. Methods Patients (aged ≥18 years) with data in selected secondary databases from 11 countries will be included if they have at least two estimated glomerular filtration rate (eGFR) measurements from 2015 onwards that are ≥30 and <60 mL/min/1.73 m2, recorded >90 and ≤730 days apart. Undiagnosed cases are those without an International Classification of Diseases 9/10 diagnosis code for CKD (any stage) any time before and up to 6 months after the second qualifying eGFR measurement. Time to diagnosis will be assessed using a Kaplan–Meier approach; patient characteristics associated with undiagnosed CKD will be assessed using adjusted logistical regression analyses. Results REVEAL-CKD will assess the point prevalence of undiagnosed stage 3 CKD and time to CKD diagnosis in initially undiagnosed cases overall and in individual countries. Trends in undiagnosed CKD prevalence by calendar year will be assessed. Patient characteristics, healthcare resource utilization, adverse clinical outcomes, and CKD management and monitoring practices in patients with versus without a CKD diagnosis will be compared. Conclusions REVEAL-CKD will increase awareness of the global clinical and economic burden of undiagnosed stage 3 CKD and provide valuable insights to inform clinical practice and policy changes.

Abstract
Heart failure and cardiovascular disorders represent the leading cause of death in diabetic patients. Here we present a systematic review of the main mechanisms underlying the development of diabetic cardiomyopathy. We also provide an excursus on the relative contribution of cardiomyocytes, fibroblasts, endothelial and smooth muscle cells to the pathophysiology of heart failure in diabetes. After having described the preclinical tools currently available to dissect the mechanisms of this complex disease, we conclude with a section on the most recent updates of the literature on clinical management.

Abstract
The pathogenesis of essential hypertension through the interaction with elements of the rennin angiotensin aldosterone system is affected by oxidative stress and inflammation. The present study aimed to assess the effects of ACE-Inhibitor, lisinopril, on blood pressure, lipid profiles (total cholesterol, triglycerides, LDL and HDL), MDA, and TAS, hsCRP, and serum leptin levels n hypertensive patients. A case control study included 100 newly diagnosed mild to moderate hypertensive patients and another 100 apparently healthy aged and sex matched subjects as controls. The patients were treated with 10 mg lisinopril orally per day for three months’ duration. Venous blood sample was taken to test levels of MDA, GSH and TAS, hsCRP, lipid profiles and leptin in the serum before and after lisinopril therapy for both patients and controls. Systolic and diastolic blood pressure were also assessed before and after lisinopril therapy for both patients and controls. In hypertensive patients treated with lisinopril, markers of oxidative stress (MDA, TAS and GSH), high sensitive C-reactive protein and leptin were all found to be decreased significantly after drug treatment (p < 0.01). Lisinopril affectively lowered systolic and diastolic BP values (p < 0.01). A significant decrease in lipid profile (p < 0.01) with a significant increase in HDL-C and TAS levels (p < 0.01) were found in lisinopril treated group in comparison with their values before treatment. Lisinopril may be used as a treatment for high blood pressure, as well as for the insulin resistance, hyperleptinemic, and low-grade inflammatory states that are associated with the disease.

Abstract
Cardiovascular diseases are the leading cause of death both in the world and in the Russian Federation. The most significant contributors to the increase in mortality are arterial hypertension (AH) and ischemic heart disease (IHD). Dihydropyridine calcium channel blockers (CCBs) are the first line of treatment for these conditions. This is noted in the clinical guidelines for the diagnosis and treatment of AH and in the guidelines for the management of patients with chronic coronary syndromes. CCBs are a heterogeneous group of drugs that have both general and individual pharmacokinetic and pharmacodynamic properties. They are used in patients with AH and/or IHD, including those with concomitant diseases (diabetes mellitus, chronic kidney disease, bronchial asthma, chronic obstructive pulmonary disease, peripheral arterial disease). Felodipine is one of the CCBs. It has a combination of clinical effects, allowing the drug to be prescribed as a first-line therapy for AH, IHD and a combination of these diseases. This is noted in the registered indications for its use. This CCB has a sufficient evidence base of clinical trials demonstrating not only good antihypertensive and antianginal potential of the drug, but also the nephroprotection and cerebroprotection properties. The nephroprotective effect of felodipine is associated with a slowdown in the progression of chronic kidney disease, and the cerebroprotective effect is associated with a decrease in the risk of stroke and an improvement in cognitive functioning. The safety profile of felodipine is favorable: peripheral edema develops much less frequently. This is confirmed by the results of comparative studies. Felodipine is recommended for a wide range of patients with AH, IHD and their combination due to such clinical and pharmacological properties.

Abstract
BACKGROUND High blood pressure is the most significant risk factor for the development and progression of chronic kidney disease (CKD). Lowering blood pressure is a goal to prevent CKD progression. This study of adults with CKD who have hypertension aimed to determine blood pressure control rates and the treatment patterns of hypertension and to explore factors associated with control of hypertension. METHODS This cross-sectional study included all non-dialysis people with CKD stages 3A to 5 under nephrology care in three public renal clinics in Queensland, who joined the CKD.QLD registry from May 2011 to Dec 2015 and had a history of hypertension. Demographic information, other health conditions, laboratory markers and anti-hypertensive medications in use at consent were extracted from the registry. RESULTS Among 1814 CKD people in these three sites in the registry who were age ≥ 18 years and had CKD stage 3A to 5, 1750 or 96% had a history of hypertension. Of these, the proportion with BP control to < 140/90 mmHg was 61.7% and to < 130/80 mmHg was 36.3%. With target BP < 140/90 mmHg or < 130/80 mmHg, participants aged ≥65 years were 1.23 (95% CI 1.06-1.42) or 1.12 (1.03-1.22) times more likely to have uncontrolled BP compared to those < 65 years old. Participants with severe albuminuria or proteinuria were 1.58 (1.32-1.87) or 1.28 (1.16-1.42, p < 0.001) more likely to have uncontrolled BP compared to those without significant albuminuria or proteinuria. Participants who had cardiovascular disease (CVD) were less likely to have uncontrolled BP compared to those without CVD (0.78, 0.69-0.89 or 0.86, 0.80-0.92). Factors associated with use of more classes of antihypertensive medicines among participants with uncontrolled BP (> 140/90 mmHg) were older age, diabetes, CVD, obesity and severe albuminuria/proteinuria (p < 0.05). Renin Angiotensin Aldosterone System inhibitors were the most frequently used medicines, regardless of the number of medicine classes an individual was prescribed. CONCLUSIONS Blood pressure control rates in these hypertensive people with CKD was still far from optimal. People with CKD and hypertension aged 65 or older or with severe albuminuria or proteinuria, a group at risk of progression of kidney disease, have higher rates of uncontrolled BP.

Abstract
Ixodes tick-borne borrelioses (ITBB) are caused by two different spirochetes: Borrelia from the group of Borrelia burgdorferi sensu lato, the agents of the classic Lyme borreliosis (LB), and Borrelia miyamotoi that belongs to the group of Borrelia causing tick-borne relapsing fevers. ITBB caused by B. miyamotoi (BM-ITBB) is a previously unknown infectious disease discovered in Russia. It is known that the LB sequelae may reduce the long-term life guality of convalescents. AIM To study the follow-up of those who have recovered from new BM-ITBB infection in comparison with persons who have had LB. SUBJECTS AND METHODS The investigation enrolled 41 patients with BM-ITBB and 41 patients with LB who were treated at the Republican Infectious Diseases Hospital of Udmurtia. Within a year after the disease, they were followed up through clinical and instrumental examination of cardiac performance, expanded biochemical analysis of blood and urine, which could; estimate kidney and liver functions, and psychological questioning. RESULTS Asthenic syndrome and complaints about and objective signs of cardiac dysfunctions persisted supraventricular extrasystoles, left ventricular diastolic dysfunction, and elevated and/or unstable systolic blood pressure were detected in 20-30% of the convalescents for a long time. Kidney dysfunctions were manifested in albuminuria and the decrease of glomerular filtration rate. A year following the disease, 10-20% patients had persistently elevated concentrations of alanine aminotransferase, aspartate aminotransferase, and C-reactive protein and had higher levels of total cholesterol and low-density lipoproteins. The pathological consequences of ITBB were polymorphic and varied in different patients; in general, only 68% of them showed health improvement. CONCLUSION We assume that a significant role in the pathogenesis of BM-ITBB and LB is played by vascular endothelial damage possibly associated with the inflammatory and autoimmune aspects of an immune response in Borrelia infection. The consequences of this damage may persist and even intensify during a year, which provokes chronic dysfunction of the heart, kidney, or liver in a number of convalescents.

Abstract
OBJECTIVE To evaluate the association between three obesity markers, body mass index (BMI), abdominal circumference (AC), waist to height ratio (WHtR), and albuminuria in adults seen in a primary health care center specialized in chronic diseases in Lima, Perú. METHODS A cross-sectional, descriptive, retrospective study in adults who attended a primary health care center specialized in chronic diseases in 2011. Patients were divided into four categories: healthy subjects and patients with high blood pressure, with type 2 diabetes mellitus (T2DM), and with both diseases (HBP+T2DM). The main outcome was presence of albuminuria, defined as urine albumin levels higher than 30mg/day. Exposure variables included the following obesity markers: body mass index (BMI), waist-to-height ratio (WHtR), and abdominal circumference (AC). Other covariates considered included sex and age. Crude and adjusted Poisson regressions were performed to estimate prevalence ratios (PRs) and their respective 95% confidence intervals (95% CIs). Areas under the curve were calculated for each indicator, stratified by sex. RESULTS Data from 1,214 patients, 41% of them male, were analyzed, and albuminuria was found in 14.2%. Albuminuria was found to be associated to AC and WHtR, but not to BMI. All three parameters assessed had similar areas under the curve. The optimum cut-off points found for BMI and AC in females were higher than conventional (32.7kg/m2 and 93cm respectively), while the values in males were lower than conventional (27.9kg/m2 and 100cm respectively). For WHtR, however, the optimum cut-off point was higher in both sexes. The higher index in females was for BMI, followed by AC and WHtR. In males, the higher index was for WHtR, followed by AC and BMI. CONCLUSIONS AC and WHtR were found to be directly associated to albuminuria, while BMI was not associated to albuminuria. Areas under the curve were similar for all three markers. The optimum cut-off points for BMI and AC were higher than the conventional ones in females and lower in males.

Abstract
The prevalence of non-communicable diseases like diabetes mellitus (DM) and hypertension (HTN) is growing worldwide. Both lead to nephropathy if not controlled effectively. Microalbuminuria (MAU) is recognized as an early predictor for nephropathy. Additionally, the timely detection of advanced glycation end products (AGEs) is also considered to be an important prognostic factor for diabetic nephropathies. Hence, screening for the early detection of MAU and AGEs would be an useful and relatively inexpensive laboratory test for early clinical diagnosis for the incidence of nephropathy in these diseases. This study was conducted in DM, HTN and pregnancy induced hypertensive (PIH) subjects. MAU and Nε-Carboxymethyllysine (CML) levels were estimated by in-house RIA kits in the patient groups and controls, while the total AGEs level in serum was determined by ELISA. The levels of MAU, CML and AGE-BSA were observed to be significantly higher in DM, HTN and PIH subjects compared to controls (p < 0.001). Increased serum CML and AGEs levels in DM, HTN and PIH subjects indicated ongoing glycemic damage and their susceptibility to develop renal complications.

Abstract
BACKGROUND Hypertension is a major public health problem worldwide and a key factor for chronic kidney disease (CKD). Detection and treatment of CKD is of paramount importance. Albuminuria is one of the earliest screening markers recommended in patients at increased risk for CKD. OBJECTIVE We conducted this study to determine the prevalence of persistent albuminuria (PA) in newly diagnosed hypertensive subjects and to study its associated risk factors. METHODS A total of 173 (72%) of 240 subjects among 1340 newly diagnosed hypertensive subjects from an ongoing community-based cohort study who had been screened once for the presence of albuminuria were retested for the presence of PA in this study. Urinary albumin concentration (UAC) in mg/L and albumin-to-creatinine ratio (ACR) in mg/g creatinine were determined in a spot morning urine sample by nephelometry. RESULTS The prevalence of PA signifying CKD was 9.3% with 95% confidence interval (CI) of 7.8-10.8% by UAC and 8.1% by ACR method (95% CI: 6.6-8.4%). Subjects with PA had mean age of 56.4 ± 11.4 years and 50% were males. Factors independently associated were male gender (odds ratio [OR], 1.92 (95% CI: 1.24-2.97)) and age less than 55 years with positive family history of kidney disease (OR, 15.51; 95% CI: 7.35-32.97). Among measurable variables, high cholesterol levels (p = 0.001), and progressively higher levels of systolic blood pressure (p < 0.001) were associated with risk of PA. CONCLUSION Hypertensive kidney damage is already present in a significant number of newly diagnosed hypertensives suggesting late detection of hypertension.

Abstract
AIM To assess the prevalence of persistent microalbuminuria (MAU), its clinical correlates by dip stick method, its predictive value for potential kidney disease and the utility of this test as objective cue for health care seeking behavior in adult Indian patients with type 2 diabetes mellitus. MATERIALS AND METHODS Approximately 400,000 patients shall be enrolled in this multicentric, cross sectional study. Patients meeting eligibility criteria shall be screened for MAU through urine dipstick test using random daytime single spot urine specimen. Result shall be expressed either positive or negative based on the presence or absence of albumin in the urine and will be correlated with the corresponding random blood glucose. Height, weight, waist circumference and blood pressure shall be assessed. There will be three visits with a minimum interval of 28 days between two visits, to be completed within 180 days, and at least two of three urine tests measured in this period must show elevated albumin levels to diagnose MAU. CONCLUSION Detection of MAU through the dipstick method is postulated to be a rapid, reliable test for early detection of diabetic nephropathy, which, in turn will help the physician to plan treatment strategy. Further, it will help to identify the disease burden on the individual and society, and may serve as an objective cue for improved health care seeking behavior, as well as a catalyst for health policy change.

Abstract
BACKGROUND The renal resistive index (RI) measured using Doppler ultrasonography has been used as a diagnostic tool in the daily work-up of kidney diseases. A better understanding of its relationship with preclinical organ damage may help in determining overall cardiovascular risk in hypertensive patients. METHODS We evaluated the association between RI and the presence and degree of target organ damage (TOD) in 288 (130 male) essential hypertensive patients. RI, carotid intima-media thickness (IMT), and left ventricular (LV) mass index were assessed by ultrasound scan. Albuminuria was measured as the albumin-to-creatinine ratio (ACR) in three consecutive first morning urine samples. RESULTS In univariate analysis, patients with TOD showed significantly higher RI as compared with those without TOD (presence vs. absence of carotid wall thickening, LV hypertrophy, and albuminuria, P < 0.01, respectively). The severity of each TOD increased progressively from the lower to the upper RI tertile. Multiple logistic regression analysis found that each standard deviation increase in RI gave a 47% higher odds of having LV hypertrophy, and a 70% higher odds of having albuminuria (P < 0.05, respectively). The occurrence of at least two signs of TOD also significantly increased in parallel with elevation of RI (odds ratio (OR): 1.89 for 1 s.d. increase, P < 0.01). CONCLUSIONS These results suggest that increased RI may be a marker of subclinical TOD in patients with essential hypertension.

Abstract
The renin-angiotensin system (RAS) plays a key role in a number of pathophysiological mechanisms that are involved in the development and progression of cardiovascular and renal disease. For these reasons, pharmacological antagonism of this system, particularly the blockade of formation or the receptor antagonism of angiotensin II, has been demonstrated to be an effective and safe strategy to reduce the burden of cardiovascular disease. Among different drug classes, angiotensin II type 1 receptor antagonists (angiotensin receptor blockers [ARBs]) have provided an excellent alternative to ACE inhibitors, representing a more selective and a better tolerated pharmacological approach to interfere with the RAS. Results derived from large, international, randomized clinical trials have consistently indicated that ARB-based therapeutic strategies may effectively provide cardiovascular and renal disease prevention and protection in different clinical conditions across the entire cardiovascular continuum. This article reviews the pathophysiological rationale of RAS involvement in the pathogenesis of renal diseases, focusing on the beneficial effects provided by ARBs in terms of renal protection.

Abstract
INTRODUCTION Measurement of microalbuminuria (MAU) is an important diagnostic tool in renal and vascular disease. This survey assessed the level of awareness of physicians in five European countries of the clinical value of MAU and its correlation with cardiovascular risk factors, disease progression and organ damage. METHODS Participants of the survey were general practitioners, cardiologists and diabetologists from France, Germany, Italy, Spain and the UK. The survey was performed via computer-assisted telephone interviews (CATIs) to ensure consistency and high quality. Participants were asked questions on MAU, its role as a risk factor, the assessment of related organ damage and measurement of these factors. RESULTS Results are presented as percentage ranges between countries and specialities. The association of MAU with kidney damage is well recognized (93.8-99.4%); however, its relationship to damage in other organs was relatively poor. Renal function is usually assessed in at-risk patients in all countries surveyed. In only 33.9-42.5% of diabetic patients treated by a diabetologist MAU was measured. The rate and method of MAU assessment varies between countries, in terms of type of urine sample, frequency of tests and number of tests required to yield a positive result. CONCLUSION Physicians have an incomplete understanding that MAU is not only a risk factor but also an important diagnostic tool for renal and cardiovascular damage. There are methodological inconsistencies in the way that MAU is currently assessed and standardization is required.

Abstract
BACKGROUND Hypertension and proteinuria are medical complications associated with the multisystemic effects of long-term hypercortisolism in dogs with hyperadrenocorticism (HAC). METHODS This study investigated the relationships among adrenocorticotropic hormone (ACTH)-stimulation test results, systemic blood pressure, and microalbuminuria in clinically-healthy dogs (n = 100), in dogs affected with naturally occurring pituitary-dependent (PDH; n = 40), or adrenal-dependent hyperadrenocorticism (ADH; n = 30). RESULTS Mean systemic blood pressure was similar between clinically healthy dogs and dogs with HAC (p = 0.803). However the incidence of hypertension was highest in dogs with ADH (p = 0.017), followed by dogs with PDH, with the lowest levels in clinically healthy dogs (p = 0.019). Presence of microalbuminuria and albuminuria in clinically healthy dogs and dogs affected with HAC was significantly different (p < 0.001); incidences of albuminuria followed the same pattern of hypertension; highest incidence in dogs with ADH, and lowest level in clinically healthy dogs; but microalbuminuria showed a different pattern: clinically healthy dogs had highest incidences and dogs with ADH had lowest incidence. The presence of albuminuria was not associated with blood pressure values, regardless of whether dogs were clinically healthy or affected with ADH or PDH (p = 0.306). CONCLUSIONS Higher incidence of hypertension and albuminuria, not microalbuminuria was seen in dogs affected with HAC compared to clinically healthy dogs; incidence of hypertension and albuminuria was significantly higher in dogs affected with ADH compared to PDH. However, presence of albuminuria was not correlated with systemic blood pressure.

Abstract
OBJECTIVE Brachial-ankle pulse wave velocity (baPWV) is a new measure of arterial stiffness. We have shown that a higher baPWV is associated with more severe albuminuria in patients with essential hypertension. However, it is still unclear as to whether baPWV predicts the future albuminuria status in patients under standard care. METHODS A total of 321 nondiabetic patients with essential hypertension who had normoalbuminuria or microalbuminuria and were receiving treatment under the current hypertension guidelines were followed up for 2 years. Resting BP, fasting blood glucose, urinary albumin excretion and baPWV were measured before treatment, and periodically thereafter for 2 years. RESULTS A 2-year treatment regimen lowered BP from 156/93 to 135/81 mmHg (P < 0.0001) and reduced the incidence of microalbuminuria from 25.8 to 14.0%. To determine the predictors for future microalbuminuria status, we compared the baseline data between patients with normoalbuminuria (n = 276) and those with microalbuminuria (n = 45) 2 years after the treatment. The microalbuminuric patients had a significantly higher baPWV and urinary albumin excretion and a significantly lower high-density lipoprotein concentration than the normoalbuminuric patients. Furthermore, the frequency of the use of renin-angiotensin system inhibitors was significantly lower in the microalbuminuric patients than in the normoalbuminuric patients. A multiple logistic regression analysis showed that higher baPWV was an independent risk factor for microalbuminuria 2 years after treatment of hypertension. When we restricted our analysis to a cohort of patients without microalbuminuria at the baseline, we found that higher baPWV was an independent predictor of the development of microalbuminuria after 2 years. CONCLUSION Higher baPWV could be an independent risk factor for future microalbuminuria in patients with essential hypertension.

Abstract
OBJECTIVE To provide an overview of current habits, priorities, perceptions and knowledge of cardiologists with regard to hypertension and stroke prevention in outpatient practice. METHODS A sample of 203 cardiologists operating in outpatient clinics and randomly selected amongst members of the largest Italian Outpatient Cardiologist Association were interviewed by e-mail, in April-May 2007. RESULTS The interviewed cardiologists reported that hypertensive outpatients represent a large percentage of their practice population, in which the clinical priority was blood pressure (BP) reduction. Stroke was identified as the most important event to prevent and it was also perceived as the most preventable hypertension-related cardiovascular event. A remarkably high rate of achieved BP control was reported, to a degree that it is inconsistent with current epidemiological reports and with the relatively low percentage use of combination therapies declared by cardiologists. Additional risk factors, organ damage, diabetes mellitus and atrial fibrillation were consistently reported in hypertensive patients. Among antihypertensive drug classes, a preference for angiotensin-converting enzyme inhibitors has been expressed by the majority of physicians; this choice was generally justified by evidence derived from international trials or by the antihypertensive efficacy of this drug class. CONCLUSIONS The results confirm the presence of weaknesses in the current services for patients with hypertension, even when being managed by cardiologists. Discrepancies between perceptions and reality, or clinical practice and guideline recommendations are also highlighted. An analysis of these aspects may help to identify current areas of potential improvement for stroke prevention in the clinical management of hypertension in cardiology practice.

Abstract
Cardiologists play a central role in managing hypertensive patients, although recent surveys reveal a marked discrepancy between cardiologists' appreciation of their patients' risk status and the measures taken to reduce that risk. The diagnosis and the management of hypertension, in fact, must be viewed today not in isolation, but as part of a patients' global cardiovascular (CV) risk, resulting from the concomitant presence of a variety of risk factors, organ damage (left ventricular hypertrophy, carotid or peripheral atherosclerosis, microalbuminuria or impaired glomerular filtration rate), and hypertension-related clinical conditions. The choice of timing and the intensity of antihypertensive treatment should be based on blood pressure (BP)-lowering efficacy and the propensity to favourably impact patient's individual absolute CV disease risk profile. As part of this paradigm shift in CV disease prevention strategy, cardiologists can take several key steps to help improve standards of hypertension control: (i) increase the awareness of total risk management; (ii) initiate an integrated management strategy tailored to the individual patient's global CV risk (e.g. hypertension, hypercholesterolaemia, diabetes, age, smoking and gender); (iii) use any elevation in BP as a gateway to begin total risk management and (iv) utilise combination therapies (particularly fixed-dose combinations) to achieve more rapid and persistent BP control and improve patient compliance/persistence with therapy. To help improve standards of hypertension control in the cardiology setting, this review examines the concept of treating hypertension using a global risk assessment approach and proposes effective hypertensive therapy as part of global risk management in patients typically seen in cardiology practice.

Abstract
OBJECTIVE Diabetes mellitus is associated with endothelial dysfunction and oxidative stress (OS). The aim of the present study was to determine whether increased OS and impaired endothelial function, are present in early states of diabetes, such as impaired glucose tolerance (IGT) and impaired fasting glucose (IFG). METHODS Brachial artery flow-mediated dilatation (FMD) and nitrate-induced dilatation were measured in 133 subjects with carbohydrate abnormalities (45 IGT, 44 IFG and 44 Type 2 diabetes mellitus) and in 46 subjects with normal glucose tolerance (NGT). Waist circumference, body mass index, blood pressure and fasting lipid profiles were obtained, and glucose and insulin values in response to a 75-g oral glucose load were also measured. Plasma malondialdehyde (MDA) and superoxide dismutase (SOD) activity were determined. RESULTS Patients with diabetes and prediabetes had a higher plasma MDA concentration, but a lower plasma SOD activity than the NGT group (p = 0.006) and SOD activity was positively associated with FMD (p = 0.039). FMD were significantly reduced in the groups of subjects with abnormal carbohydrate metabolism compared with the NGT group (p = 0.035). Among the subjects with diabetes and prediabetes, FMD showed a negative correlation with fasting glucose and/or plasma glucose level at 120 min after oral glucose tolerance test (p = 0.028). CONCLUSIONS The results showed that endothelial dysfunction and increased OS were present in subjects with IGT and IFG, indicating endothelial damage in these stages.
